Cluster validity index based on n-sphere
(
IEEE
, 2014 , Conference Paper)
In this paper, we propose a new cluster validity index (CVI) based on geometrical shape. Classic CVIs are based on a combination of separation and compactness measures and may include a measure of overlap between clusters. ...
Vector anisotropic filter for multispectral image denoising
(
SPIE
, 2015 , Conference Paper)
In this paper, we propose an approach to extend the application of anisotropic Gaussian filtering for multi- spectral image denoising. We study the case of images corrupted with additive Gaussian noise and use sparse matrix ...
Experimental prediction of the elastic properties of nanocomposite cementitious materials based on nanoindentation measurements
(
American Scientific Publishers
, 2017 , Article)
This paper provides in depth novel exploration of the local mechanical properties of nanocomposite cement using the nanoindentation technique. The elastic properties of carbon nanotubes (CNTs)-reinforced and unreinforced ...
Photoactuating of materials designed for haptic aid-tablets for visually impaired people based on styrene-b-isoprene-b-styrene block copolymer nanocomposites
(2013 , Article)
In this study, the photoactuation of styrene-b-isoprene-b-styrene (SIS) block copolymer containing multiwalled carbon nanotubes (MWCNT) is shown. In order to improve dispersion, the MWCNT were ovalently modified either by ...
Computational Simulation Of Organic Rankine Cycle Retrofitted To Petroleum Well
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Geothermal refers to existing heat energy in deep rock and sedimentary basins. Unlike other types of renewable energy resources, geothermal energy provides a stable source of energy as it can be exploited regardless of ...
Self-standing elastomeric composites based on lithium ferrites and their dielectric behavior
(
American Institute of Physics Inc.
, 2014 , Article)
Lithium ferrite (LiFe5O8) is an attractive material for technological applications due to its physical properties, which are significantly dependent on the preparation method and raw materials. In this work, LiFe5O8 ...
Electrical properties of lithium ferrite nanoparticles dispersed in a styrene-isoprene-styrene copolymer matrix
(
Springer Netherlands
, 2015 , Book chapter)
The main goal of this work was the preparation and study of a composite material by dispersing lithium ferrite particles in a polymeric matrix. The matrix selected was styrene-b-isoprene-b-styrene (SIS) copolymer. Lithium ...
A Hardware Based Ricean Fading Radio Channel Simulator
(
IEEE Xplore
, 2017 , Conference Paper)
The rise of the need of fading radio channel simulators is due to time and cost of field tests of wireless communications systems. Growth in the demand for fixed wireless access increases the need for wide area system ...
Social robots and wearable sensors for mitigating meltdowns in autism - A pilot test
(
springer link
, 2018 , Conference Paper)
Young individuals with ASD may exhibit challenging behaviors. Among these, self-injurious behavior (SIB) is the most devastating for a person’s physical health and inclusion within the community. SIB refers to a class of ...
Toward 3D Printed Prosthetic Hands that Can Satisfy Psychosocial Needs: Grasping Force Comparisons Between a Prosthetic Hand and Human Hands
(
springer link
, 2017 , Conference Paper)
The advancement in 3D printing technologies appears to be the key toward affordable and functional artificial limbs. The loss of an amputee’s capability to do functional tasks like grasping objects has an obvious effect ...
